G'day Mandy,Just a minor point about the words:
"and your belly's row-in fu'..." I have always taken as: "and your belly's rollin fu' (rolling full) ..." i.e. she is heavily pregnant and thus not able to do very heavy work (although I once knew a lady, from the south of England, whose grandmother went back to work in the fields after giving birth during the lunch break!).
